My 2011 27 inch iMac which was purchased in February 2012 is not turning on. I have never had a problem with it until now. I was working on Bootcamp and when I restarted the computer, it froze at the login screen so I force restarted the computer by pressing the power button down for 10 seconds. When I restarted the computer it did not want to turn back on. The only thing that happens when I restart much computer is I hear something that normally sounds since I purchased the computer which is either the hard drive or the DVD drive but no white screen comes up. I have tried to pull the power plug for 15 seconds and then plug it back into the back of the computer and wait five seconds before turning it on and I have also tried restarting the computer while pressing command option P and R. I removed the memory sticks and put them back in properly get the computer still did not turn on. I have a 27 inch mid 2011 iMac running Mac OS X 10 7.4. It is a quad core I73.4 GHz with 16 GB of RAM 256 GB factory installed SSD +1 TB hard disk drive with the AMD 6970 and 2 GB graphics card. Sorry for the long post.!I wanted to be as descriptive as possible as I am really trying to avoid bringing it to the Apple Store because I need the computer because I go to school online and have finals this week.

My Mid 2011 iMac 27" i7 will no longer start after the latest EFI update. I decided to perform some system updated on my iMac and after installing 10.7.3, I rechecked and it found the EFI update and one other update. They were both pretty small (the largest was 3.6MB), so I decided to proceed prior to getting back to business with my system. After downloading the updates (took about 5 seconds), the machine proceeded to restart. There was a loud beep prior to the system restart chime after which it went to the grey-white apple startup screen with the spinning wheel. And it stayed there. After 35 minutes with no discernable progress, I decided something must be wrong. This system normally takes about 30 seconds to boot from a cold state (it's running on an OWC SSD) or maybe a minute after updates. So I held the power button to reboot. But it keeps going to the same state. I tried to reboot to a different internal drive holding the option key, but the same thing happens.Â

1. How do I recover from this?
2. Is anyone else running into this problem?
3. How long do the EFI updates normally take?
4. Shouldn't there be some sort of "progress bar" to indicate something is going on during this process? Or, if not, then perhaps a "WARNING!! This process will take up to two hours, during which you will receive no discernable feedback. Do not interrupt the process until more than 24 hours have passed with the spinning ball."Â Â
P.S. I think this is my last iMac EFI update. After my last iMac received an EFI update (2009 model 24" iMac), it became ultra-flakey and started corrupting HD's. It never worked the same after that. This machine was working PERFECTLY before the update.
So, for the last two months my iMac (27", 2,7 GHz, mid 2011, 12 GB RAM, AMD Raderon HD 6770M 512MB, running OSX Lion 10.7.3) has started to freeze during games and from time to time during youtube videos or VLC. A reboot is required, but the problem usually comes back within 5 minutes or so.Â
The game I play is usually StarCraft 2, which worked fine for about 6 months before the freezes started. Most of the time the computer just freezes but sometimes the right side of the screen is moved to the left side and the left to the right. Then the freeze occurs, the screen turns grey with small vertical stripes on it. Graphics hardware problem?Â
No swaps of the screen occurs during the freezes when watching video but everything else is pretty much the same. After a few freezes the iMac refuses to reboot for a couple of hours.Â
Installed the update and what wasn't a problem is now a problem. The computer will not connect to wifi without me telling it to after coming out of sleep. Was not an issue with 10.7.2.
I purchased an iMac last October and my line of work demands extensive use of After Effects and Final Cut Pro. My iMac is fitted with the standard 1TB SATA hard drive, and lately I considered installing an SSD drive as I have been experiencing lags. In all my naivete I asked Apple Store/Service outlet where I originally bought my iMac, but they turned me down, claiming that "they are not allowed to order the extra parts and if they do proceed then my warranty will be void". Which means that about 2 years of AppleCare will go out of the window. I can always do it myself, but at the risk of damaging my iMac and facing a null warranty on top of it. I am still reeling in disbelief, is it really the case that Apple prohibits its customers from legitimately upgrading their computer at their own stores?
I am running Lion 10.7.3 on a 2.8GHz CoreDuo iMac from 2007 and on a Macbok Air 2.13 GHz Core duo from 2010. The iMac has 4GB of RAM the Macbook has 2 GB RAM.Â
I run Microsoft Office 2011 on both machines. For the same file the Macbook operates normally on Word and Excel. The iMac is slow at best and when I try a Save As it hangs for up to 15 minutes brfor letting me change the FIle Name. This effectively makes it unusable.Â
As far as I can tell the set up of Office on both Machines is identical and I have eliminated duplicate Fonts as suggested by some posts but the problem remains. I have checked Activity Monitor and I am not getting any Page Outs so RAM does not appear to be an issue.
after bought external drive and back up all my macHD , did ask couple question with Apple IT person at Apple store about trying to format my hardisk on my Imac, and deleted some files and try to restart and turn out Imac didn't restart and all I get is black screen with flashing dash looks like I'm in terminal mode or something and my keyboard is not respond too.My Imac model is iMac 7.1, Intel Core Duo 2,4 Ghz also just update my leopard to Lion last year.
I've just ordered an i5 Mac Mini and while it's destined to be used as a media-centre/ streamer connected to my TV via HDMI, initially I want to hook it up to the display on my 2011 iMac. Can one of you clever bods point me in the direction of what cable I need, and also what do I need to do to the iMac to make it behave as just a monitor? Is it just a matter of plugging in the cables and off I go?
I upgraded to Snow Leopard a few days ago, my Imac is from 2008, and today, I upgraded to Lion, and just when the computer rebooted, it got stuck in some form of reboot screen, dark, bunch of code. What do I do now? Do I need to turn it in?
So as the title says when I boot up my iMac, on occasion, it seems to have the "Updating" Status bar, then the mac boots normally, then the sound is disabled. As I said though this dose not happed all the time but when it dose the only way to fix it is by rebooting the iMac once again.

It was purchased brand new. I used it for one hour yesterday, run the set up, install updates. thats all I have done with it. Today I awake to it presenting a loading bar of some sort under the Apple logo and Spinning wheel. I researched the bar, and found that it was a progress bar for a disk check, and since it doesnt complete (I let it do its thing) something must be wrong, However when i run disk utility, it can find now error in the disk. but my sound and video play pack does not work unless i restart the machine. this seems like an unessecary process. what are the possible causes?
How do I start iMac in a basic mode with no extensions or startup programs. I had it freeze when " Little Stitch" started to run and asked to open a Port. Then freeze.
i got from My Aunt an Old iMac G5 (Not Intel ), befasse she Knows that i ' m Fanboy ;). Now this beautiful machine ist Too low, that why i want to use the Monitor for My MacBook pro 2011. Can i do it ? Is there Software? How can i make it.
This has been going on for me for the past few months on and off, it just randomly switches the screen off but everything else works perfectly, for example if im watching a video on hulu i can still hear the sound, if im doing work on word the documents are still there, iv finally gotten video footage of it. url...To turn it back on i press "ctrl + shift + eject" and then move the mouse. i have contacted Apple support on the phone they did say bring it in, just need to make an appointment. If anyone else has this problem and knows a better solution than having to keep pressing buttons to turn the screen back on please share.
We have just purchased a refurbished 2011 27" i5 iMac. It comes with 4GB of ram standard. As I don't want to waste that ram when we upgrade it, I was wondering if I could use it in my early 2009 macbook.I've checked on crucial and the macbook will accept 4GB of ram. There is a similar question on this forum, but the answer was ambiguous. I have also trawled a really useful forum on macrumors, but it wasn't clear whether it could accept it or not.
i was wondering if it's possbile to connect 2 thunderbolt displays (daisy chained) and a DVI screen to the second thunderbolt port at the same time on an iMac 27" mid2011?I tried searching, but I didn't find anything about it. At the moment I have 1 thundebolt and the DVI screen (55" HDTV Full HD) using both thunderbolts, but if I could connect a second thunderbolt display, or eventualy a Cinema LED 27" it would be very useful.
I have accidentally wiped the hard drive of a mid 2011 imac 27" there was no install DVD provided for this machine and a retail Snow Leopard disk will not boot, apparently I need 10.6.8 and the retail disk is only 10.6.3 is there any solution to this dilemma?
I am having finder freeze all the time.I am using Lion and am new to Mac in general.I try to force quit and relaunch but it will hang the system forcing me to power it down.
I need to purchase a replacement LCD for my iMac 21.5" I have found cheaper LCDs for the the 2009 and 2010 iMacs. I was wondering if they will work on my 2011 model. The lcd numbers are the same exept for the () numbers. The 2009 lcd number is LM215WF3 (SL) (A1). The lcd on my mac is LM215WF3 (SD) (C2). Will any 21.5" work?
My small business has an office iMAC and a Macbook Air both running 10.6.8. The two aren't synced in any way other than that the Air can access files from the iMAC's hard drive via the network. I have 2 email accounts on the iMAC's mail and just one of them set up on the Air.Â
I've just bought a new 15" Macbook Pro running Lion. I'd like to be able to sync some folders (but definitely not all), bookmarks, iTunes and mail accounts between the iMAC and the new Macbook Pro. Ideally I'd like to be able to access the shared/synced folders when I don't have an internet connectionÂ
What's the best method?Â
Snow Leapord doesn't have iCloud does it? If not, why the **** not?Â
Is it just easiest to set up the email accounts on the new MBP as normal and then use dropbox for the folders I want to share? Can I access the with no internet connection?Â
One other question, can i link a gmail account to my Apple mail? Dave.
I read that it is possible by using a dongle, then I read it doesn't work.....Thought I would ask the people who might actually know if this is something that can be done. I am about to upgrade to OS X and would like to benefit from the new "handoff" feature in Yosemite.
My iMac mid 2011 does not read the SD Card. In 'System Info' the info abou card reading device tells: 'This computer does not have integrated Apple card reading devices' (something like that, my OS is in Russian).
Worked great a couple of weeks ago, now I have that issue. Is there a way to fix that without changing my iMac's elements?
I have a G5 iMac - 2.1 ghz, 20", 250gb hd and 3gb ram, but it has been having problems starting up and it is also going to sleep midway through a task or at random times totally unprompted.
It now almost never starts up first time (I keep the iMac mains power lead always connected and the mains electricity supply turned on at all times now)- sometimes I will get the 'Start-up Chime' and then the cooling fans start spinning very loudly and then after a few seconds the iMac stops the start-up routine, but often when I try to start-up I don't even get the 'Start-up Chime' and I have to leave it for some time before trying again.
I can also now only get the iMac to run as a Firewire Target Disc by starting up with the T key held down and then using an old G4 (400mhz) Powerbook Titanium as the screen/keyboard by using the iMac HD as the startup disc for the Powerbook but this is obviously just a temporary work around.
I have also tried backing up all my data, and reinstalling the Mac OS X onto the iMac but the iMac still will not start-up normal and I still have to use it just as a Firewire HD.
I have a 500 GB Hard drive in my early 2011 MacBook Pro and will be adding a a second SSD Drive in the former location of my optical drive. I purchased a 64GB SSD and only want to transfer the operating sytem and apps. How can I do this? I am familiar with super duper but think that only exact copies can be made. Is there any other way that I can transfer just Mac OSX Lion and my Apps to my new hard drive?Â

I have an Intel IMAC, which is now out of warranty as I have had it for 16 months (and I was dumb enough not to get AppleCare). A few days back, my computer would not startup and everytime I hit the power button, I would hear some spinning noise but no chime from the iMAC. Yesterday, I tried it again and this time I heard the chime but the monitor did not start. I was then able to SSH into the MAC and see that it is indeed connected to the network and booted up, but the screen is still dead. Any ideas what I should do before the painful trip to the apple store ?
